GENERAL HISTOLOGY

Detailed explanation-1: -Each of our body systems are interconnected and dependent on each other. Our heart, which is part of our circulatory system, does not beat unless our brain, which is part of our nervous system, tells it to. Our skeletal system is dependent on our digestive system for increase in size and strength.

Detailed explanation-2: -Some body systems work together to complete a job. For example, the respiratory and circulatory systems work together to provide the body with oxygen and to rid the body of carbon dioxide. The lungs provide a place where oxygen can reach the blood and carbon dioxide can be removed from it.

Detailed explanation-3: -The nervous system controls various organs of the body directly. The brain also receives information from many organs of the body and adjusts signals to these organs to maintain proper functioning. The skeletal system makes up the framework of the body and allows us to move when our muscles contract.

Detailed explanation-4: -A system is an organization of varying numbers and kinds of organs so arranged that together they can perform complex functions for the body. Ten major systems include the skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, and the reproductive system.
